I also hate PWAs but "Cashu" didn't rug you.

The update to the PWA randomly gave me a new Wallet after accepting the terms and conditions for a 2nd time. My guess cashu has a bug that causes the wallet to reset make the user go through the onboarding again and gives them a new seed
So technically no they didn’t rug me but the software reset my wallet when I didn’t ask it to. Thus it’s a software bug
